三个等涡四涡问题的对称相对平衡
Symmetric Relative Equilibria in the Four-Vortex Problem with Three Equal Vorticities
摘要:
我们详细研究了四涡问题的相对平衡,当三个涡具有相同的强度,即$Γ_{1} = Γ_{2} = Γ_{3} = 1$,和$Γ_{4}$是一个真正的参数。我们给出了相对平衡点和分歧值的确切个数。我们还研究了涡旋菱形问题的相对平衡。
英文摘要:
We examine in detail the relative equilibria of the 4-vortex problem when three vortices have equal strength, that is, $Γ_{1} = Γ_{2} = Γ_{3} = 1$, and $Γ_{4}$ is a real parameter. We give the exact number of relative equilibria and bifurcation values. We also study the relative equilibria in the vortex rhombus problem.
